4. Enter the following:
n
Search for Hubs every .... sec : Specifies how often the AnywhereUSB Manager
searches the local network to discover AnywhereUSB Hubs and refresh the
AnywhereUSB Manager display. Default and minimum values are both 30 seconds.
Note You cannot manually perform a refresh of the Hubs displayed in the
AnywhereUSB Manager .
n
Wait for Hub response for .... sec : Specifies the time interval from the last discovery
refresh that the AnywhereUSB Manager will stop looking for more Hubs. Default and
minimum values are both 4 seconds.
n
Send Keep-Alive every ... sec : Specifies how often the AnywhereUSB Manager sends
a keepalive request to the Hubs connected to the network. This impacts network
utilization because each
AnywhereUSB Manager will send one packet at this interval to
each Hub to which it is connected. Default is 3 seconds. The minimum value is 1 second.
n
Keep-Alive Timeout ... sec : Specifies how long the AnywhereUSB Manager should
wait for a keepalive response. When the value of the response time is reached, the
Manager decides that a Hub is no longer available, and the computer is disconnected
from all groups and devices on that Hub. The default value is 20 seconds. The minimum
value is 15 seconds.
l
The keepalive timeout value would need to be longer if the network has more
latency (such as a cellular or satellite link), or an internet link with unreliable packet
delivery.
l
If the value is too short, devices will be disconnected, which may have an adverse
affect on some devices, such as USB memory.
l
If the value is too long, Hubs that are removed from the network will not be noticed
as gone for a long time, and devices that are no longer connected will be
unresponsive for a long time.
n
Power cycle off time : Specifies the length of time between when a USB device is
powered off and then on during a power cycle. The default is 3 seconds. For information
about this feature, see

5. Click Save .
Cycle the power to a USB device connected to the Hub from the
AnywhereUSB Manager
This feature enables you to power cycle a selected USB device from the AnywhereUSB Manager .
The USB device can be connected directly to the AnywhereUSB Hub or to a downstream USB hub.
This resets the USB device and has the same effect as removing the USB device from the Hub and
then reconnecting it.
Note If an externally powered USB device (one that is not powered by the Hub) is connected to the
Hub, the power cycle feature may have no effect on the USB device.
The USB device you choose to power cycle must be assigned to a group that you are allowed to
access. When you use this feature, the power supplied by the port to the USB device is turned off and
then turned on.
